MULTIPLE-SASH-OPERATING DEVICE.

Specification of Letters Patent.

Patented May 11, 1915.

Application filed September 19, 1914. Serial No. 862,574.

To all whom it may concern Be it known that we, Josnrri MATTHEWS, EDWARD\V. FREEMAN, and WILLIAM H. S. BATEMAN, citizens of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented new and useful Improve ments inMultiple-Sash-Operating Devices, of which the following is aspecification.

The invention relates to devices for window sashes and the like, and hasfor an ob ject to provide a device for readily and effectively operatingwindow sashes to secure the same in open, closed or adjusted positionsrelatively to the frames thereof.

The invention contemplates, among other features, the provision of adevice which preferably is arranged to simultaneously operate a numberof similar sashes and'which, therefore, in its use and adaptation towindow sashes, transoms or other similar structures, will effectivelyoperate and be common to a large number of adjacently arranged sashes orother similar structures.

To this end use is made of a number of co operating arms or leverscommon to a single operating mechanism which, when operated, willsimultaneously open, close or secure in desired positions the varioussashes with which the cooperating arms or levers have connection.

In the further disclosure of the invention reference is to be had to theaccompanying drawings, constituting a part of this specication, in whichsimilar characters of reference denote corresponding parts in all theviews, and in which:

Figure 1 is a fragmentary perspective view, looking at the device fromthe rear, with parts broken away to disclose the underlying structure;Fig. 2 is a horizontal sectional view of the device shown in Fig. 1,looking down upon the operating mechanism, with the same shown to securethe sashes in open position; Fig. 3 is a similar view, the sashes beingclosed; Fig. dis a vertical sectional view taken on the line 4- 1 inFig. 2; Fig. 5 is a vertical sectional view taken through one of theclamps, on the line 55 in Fig. 2; Fig. 6 is a view looking at the sideof the cable operating structure, one of the supporting brackets thereofhaving been previously removed; Fig. 7 is a view of the sheave throughwhich 'oneend of the cable passes; Fig. 8 is a detail vertical sectionalview of the clamp connecting the toggle lever with the operating rod;Fig. 9 is a plan view of a modified form of the clamp shown in Fig. 8;Fig. 1.0 is a vertical sectional view taken on the line l0-10 in Fig. 9;Fig. 11 is a bottom plan view of the structure disclosed in Figs. 9 and10; and Fig. 12 is a vertical sectional view of a clamp showing amodification of the clamp shown in Fig. Sand which is a slightmodification of the structure shown in Fig. 10.

Referring more particularly to the views, we disclose a frame 10 forminga series of openings 11 in which are arranged sashes 12, eachbeingindependently mounted to swing in the various openings in the frame 10,and being preferably adjacently arranged, with intermediate uprights 13provided to form the openings 11 in which the sashes 12 are adapted tooperate. Secured to each upright on its inner face is a bracket orsupport 1 L having upper and lower projections 15, and pivoted to swinghorizontally on the upper projection of each bracket are a plurality ofdiverging arms 16, each having their free ends 17 ofi'set as shown andhaving pivoted on the offset ends suitable clamps 18 to which aresecured the inner ends of rods 19 having their outer ends in pivotalconnection with adjacent sashes 12 through the medium of ears 20 on thesashes, it being understood that one of the arms connected with one ofthe sashes is connected to one of the clamps onthe offset end of one ofthe arms 16, whereas the rod connected with the next adjacent "sash hasconnection with the clamp 011 the offset end of the other end pivoted onthe upper projection of the bracket. A plurality of similar togglelevers 21 are relatively pivoted at their knuckles 22 and have theirrelatively diverging ends 23 pivotally connected with the arms 16 atsubstantially their medial portions, the inner ends of the toggle leversbeing offset in opposite directions, so that one end 24 of one of thetoggle levers will project upwardly and the other end 25 of the othertoggle lever will project downwardly. Brace rods 26 are provided.

for each of the toggle levers, with the said brace rods at their endsbeing relatively pivoted on to the lower projection 15 of the bracket 14and being adapted to diverge and The outer offset ends of each togglelever 21 have pivotally arranged thereon a clamp 27, with the clamp onthe upwardly project-- ing toggle lever being arranged to encircle a rod28 and the clamp on the lower projecting togglelever arranged toencircle the rod 29, the inner ends of the said rods being connected bya cable 30 which passes over a sheave 31 journaled in a bracket orsupport 32 on the frame 10. Similarly, the other ends of the rods 28 and29 are connected by a chain 33 which is wound around a sprocket wheel 34journaled on a bracket or support 35 secured to the other end of theframe 10, said drum having a toothed wheel 36 revoluble therewith, withthe toothed wheel in mesh with a worm 37 journaled on the support 35 andcarrying on its free end an operating wheel 38, over which preferablypasses a hand cable 39 or the like, whereby rotation is imparted to thewheel 38. Now it will be seen that when the wheel 38 is rotated,rotation will be imparted through the medium of the wheel and worm 36,to the drum 3 1 and which, having the cable 39 wound around the same,will result in the rods 28 and 29 being moved in opposite directions,thus simultaneously swinging the inner ends of the toggle levers 21 inopposite directions to simultaneously move the adjacent sashesrelatively to the frame so that the sashes can be swung inwardly oroutwardly with respect to the frame and be held in an adjusted positionwhen the pull on the rods 28 and 29 is discontinued by discontinuing therotation of the wheel 38.

As mentioned heretofore, we preferably employ a large number of thesashes arranged in a horizontal line, one adjacent the other, and byemploying the operating mechanism described and the means connecting theoperating mechanism with the sashes, it will be seen that the sasheswill all be common to a single operating mechanism and thus will besimultaneously operated through the medium of the toggle levers, armsand rods which cooperate and are mounted to produce the desired result.

In Figs. 9, 10, 11 and 12 there are shown modified forms of the clampshown in Fig. 8 and which forms of clamp maybe used in place of theclamp 18 or the clamp indicated by the numeral 27 in Fig. 8, said clamp18 connecting the arm 16 with the rod 19 as shown in Fig. 1 and saidclamp 27 connecting the rod 28 with the arm 24:.

The modified form of clamp shown in Figs. 9, 10 and 11 is preferablyused to replace the clamp 18 and is therefore indicated by the numeral18" and consists, in detail, of a lower transverse grooved plate 18 andan upper transversely grooved plate 18 which plates,when arranged toabut against each other, have their transverse grooves forming anopening 18 through which the rod 19 is adapted to extend, said plates 18and 18 being held together by a transverse bolt 18 carrying a suitablenut 18 with the upper plate 18 having a forwardly extending tongue 18passing beneath a head 18 formed with the lower plate 18', as will beclearly seen by referring to Figs. 9, 10 and 11. Carried loosely on thebolt 18 is a member 18 forming a portion of the arm 16 and wherebyconnection between the rod 19 and arm 16 is secured. The structure shownin Fig. 12 is preferably used to connect the rod 28 with the lever 21 atits end 24, thus replacing the clamp 27 shown in Fig. 1 and in detail inFig. 8. This clamp is indicated by the numeral 27 and consists of alower transversely grooved plate 27 and an upper transversely groovedplate 27, with the transverse grooves of the plates, when they areconnected, forming an opening 27 through which the rod 28 passes to beclamped between and by the upper and lower plates 27 and 27. Atransverse bolt 27 passes through the plates 27 and 27 and is secured bya suitable nut 27. The upper plate 27 has a forwardly extending tongue27 similar to the tongue 18 shown in Fig. 9 and which tongue passesbeneath a head 27 b similar to the head 18 shown in Fig. 10. A member 27encircles the bolt 27 and forms a part of the end 24 of the lever 21shown in Fig. 1.

Thus it will be clearly seen that although we preferably employ theclamps 18 and 27, we can also very readily employ the clamps 18 and 27indicated in Figs. 9 to 12 inclusive, either of which sets of clampswill readily perform the function for which they are desired and resultin the parts which they associate being relatively operated to securethe most effective result with the least possible movement.
